Definitions:

Squirrel-Cage Rotor

A type of rotor in an induction motor, characterized by its cylindrical shape with conductive bars running the length of the cylinder and connected at both ends by conductive rings, creating a cage-like appearance.

Frequency

The number of cycles (of a repeating event) per unit time, measured in hertz (Hz) in the context of waves or electrical signals.

Synchronous Speed

The rotation speed at which the magnetic field in the stator rotates in synchronous machines, typically equal to the AC supply frequency divided by the number of pole pairs.

Synchronous Motor

An AC motor that operates at a constant speed, set by the power supply frequency, and whose rotor is synchronized with the magnetic field of the stator.
